Arduino Mega 1280

The Arduino Mega 1280 is based on the AVR ATmega1280 microcontroller.

Note: the AVR backend of LLVM is still experimental so you may encounter bugs.

Installing dependencies

The Arduino Mega 1280 needs a few extra dependencies to work, for example, if you get an error like this:

/bin/sh: 1: avrdude: not found

To fix this, see the installation guide for Linux and for macOS.

Flashing

AVRDude

Programs are loaded onto the Arduino Mega 1280 using the avrdude command line utility program. You must install this program before you will be able to flash the Arduino Uno board with your TinyGo code.

Plug your Arduino Uno into your computer’s USB port.
Build and flash your TinyGo program using tinygo flash -target arduino-mega1280 /path/to/code
